Section 1

Project Description

The Pearl, Qatar is a 400 hectare man-made island located off the Eastern coast of Qatar approximately 20 kilometers north of the Doha central business district and east of the West Bay Lagoon. The Pearl Island is connected to the mainland by a causeway. This island is being developed (United Development Company) to include residential and commercial usage arranged around three primary marinas, including hotels, shops, and residential villas and apartments.

The roads and infrastructure for The Pearl Island development were completed under a separate contract to support the entire island. The road work consists of roads, bridges, underpass, culverts, surface water drainage, signage, and roadway lighting. The infrastructure work consists of potable water, sanitary sewer, irrigation transmission, chilled water distribution, telecommunications civil work, and electrical distribution.

Chilled water has been a primary medium for the transfer of heat from building coils to the refrigeration system since the beginning of heating, ventilating, and air-conditioning design. Providing chilled water from a centrally located plant is an energy efficient and low maintenance means of rejecting heat from air-conditioning systems across a localized campus, whether that campus is a university setting, industrial complex, or large urban site. Over the last five years or more, district energy has exploded on to the scene in the Middle East becoming a necessary utility for new developments.

The Integrated District Cooling Plant (IDCP) at The Pearl Project includes a new central chilled water plant to serve the cooling needs for the proposed building construction on the island. Qatar Cool will own and operate this plant upon completion and have established a design-build

Q06024-IDCP-RPT-GT-001-REV 3 1-2 Stanley Consultants

contract with C.A.T. International for the construction of this plant. The new development consists of several high-rise buildings and villas, which will use the chilled water from the IDCP to serve their air-conditioning needs in the most efficient manner possible. Each building will include an energy transfer station or heat exchanger as the point of use for chilled water.

The chilled water generated at this facility will be provided for the following:

Customer loads at energy transfer stations or heat exchangers.

Customer loads at valve pits (Take-off Chambers).

Plant cooling system including, air handling units and fan coil units.

The IDCP is arranged on site to accommodate the construction of the buildings and the island roads and infrastructure and the plant will architecturally be tied into the aesthetics of the surrounding building structures. The plant will have a guaranteed capacity of 115,000 tons expandable to 120,000 tons (ARI Tolerance) using forty-six (23 pairs) 2,500-ton nominal electric motor-driven centrifugal chillers. Provisions will be incorporated into the design of the IDCP for future expansion using two 2,500-ton nominal electric motor-driven chillers. The chillers will be in a series-series, counter flow arrangement utilizing a direct primary pumping scheme.

The heat picked up by the chiller refrigeration cycles will be rejected via twenty-four 5,000-ton cooling tower cells. Each cooling tower cell will serve up to two chillers and will be piped in a headered arrangement such that each cell can be used with any combination of chillers. The cooling towers will be constructed of fiberglass and will be field-erected on the roof of the plant to conserve space on the site for other use. Aesthetic enhancements to the new building will visually compliment the architecture of the area per UDC approval.

Utilities serving the IDCP will be installed by the Infrastructure Contractor under a separate contract with the Owner. The chilled water distribution system will routed to a vault at the limits of the plant site as depicted in the Conceptual Design Drawings.

The plant will hydraulically operate as two independent facilities; each connected to new underground chilled water distribution systems. Chilled water will be delivered to network through a constant flow, direct primary pumping scheme. The Pearl Chilled Water Distribution System will be a looped, underground distribution network served by the IDCP and installed under a separate infrastructure contract as described above.

New high-voltage transformers will be provided by the infrastructure contractor and connected to the IDCP to serve the power requirements of the plant.

The control system will utilize a SCADA control system for monitoring and operation of the new equipment, except for the chillers, which will be started locally. This system will allow control of the new facility from operator workstations, located in the new plant control room. The system will utilize digital communications for remote monitoring and/or control of the various systems within the plant.

Section 2

Civil Engineering and

Landscaping Design Statement

General This section of the Design Intent Report includes the narrative description of the Civil Engineering and Landscape Site Planning for the Integrated District Cooling Plant (IDCP) at The Pearl, Qatar. Site survey data obtained during the course of this project will form the basis for the development of the grading and paving design. Discussions between the Owner, Qatar Cool, PMC, the Contractor, C.A.T. International (CAT), and the Design-Build Engineer, Stanley Consultants are detailed in Exhibit A Project Correspondence.

Compliance Statement The Civil Engineering and Landscape Site Planning design will comply with all portions of the Tender Documents prepared for Qatar Cool and issued by DAR during the tender phase. These documents include the general requirements, tender specifications, tender drawings, and the appropriate addendums and tender circulars issued for clarification, except as noted below:

Plant Arrangement: The IDCP will be based upon the plant arrangement from the Alternate 2 bid proposed by CAT and accepted by Qatar Cool prior to contract award.

Site Layout: The latest revisions to the U-07 plot limits will form the basis of the site layout and grading and paving design.

Access Road Width: Service access roads around the plant will be wider than 6 meters at areas designated for equipment installation and removal from the plant building as indicated in Section Q0547/a-SPC-TR-01 REV 1 of the Tender Specifications. Paved equipment staging areas will be provided at these locations to facilitate those operations.

Q06024-IDCP-RPT-CI-001-REV 3 2-2 Stanley Consultants

Traffic Control Construction activities will be coordinated to minimize the impact on traffic flow in the vicinity of Plot U-07. In general, traffic generated by the IDCP is low and as such is not expected to impact the traffic of the area surrounding Plot U-07.

Paving A new service access drive will be provided to the site from the north and will serve the normal operational traffic of the IDCP as well as to support maintenance and delivery activities for the plant.

All paving will conform to local codes and standards as well as Section 6 of QCS 2002.

Drainage The drainage collection system will run along the roads surrounding the site and will consist of storm sewer piping, manholes, gullies, and swails. Storm water run-off will be collected by the gullies and swails. Manholes will be placed not more than 75 meters apart and will be used for inspection of the storm water system.

Landscaping The soft landscape at ground level will use tree groups in stone mulch (10-cm crushed stone mulch to cover all unplanted and unpaved areas), towards the plot boundaries, providing framed views of the building, with ground cover and shrubs closer to the building, screening the service ring road and providing the first tier of planting to the building. Trees should be of a single, spreading, flowering variety, shrub to comprise a single type of ornamental grass such as Pennisetum alopecuroides, and ground cover of a spreading flowering succulent variety. The same ground cover and ornamental grass shall be used to the planter behind the battered ground floor parapet wall. All planting for the project will be appropriate to the exposed seashore conditions of the site and island. Trees to be minimum 250-cm overall height, shrubs and ornamental grasses grown.

The IDCP building will include planters as required to meet the agreed upon architectural appearance of the plant relative the surrounding area.

Architectural Design Statement

General This section of the Design Intent Report includes the narrative description of the architectural design for the Integrated District Cooling Plant (IDCP) at The Pearl, Qatar. Discussions between the Owner, Qatar Cool, PMC, the Contractor, C.A.T. International (CAT), and the Design-Build Engineer, Stanley Consultants are detailed in Exhibit A Project Correspondence.

The IDCP will be designed as an attractive, functional, building that acknowledges and expresses the buildings purpose. The new building and cooling towers should be considerate of the appearance, scale, and other features of the surrounding structures and at the same time, minimize the impact of the building on the surrounding visual and aesthetic environment, as well as provide for future horizontal expansion.

Compliance Statement The Architectural design will comply with all portions of the Tender Documents prepared for Qatar Cool and issued by DAR during the tender phase. These documents include the general requirements, tender specifications, room data sheets, tender drawings, and the appropriate addendums and tender circulars issued for clarification, except as noted below:


Building Exterior The design must consider the buildings physical and visual impact on the site and its relative scale to surrounding structures.

There are three main components to the proposed building; the operational plant, the cooling towers and the Administration Building.


The operational plant is a two floor building; ground with a double height, first and partial basement.

There are two rows consisting of 12 cooling towers each that sit on top of the operational plant.

The Administration Building is a three floor building; ground, mezzanine and first.

The exterior is concrete structure and blockwork with grooved plaster and paint finish, in addition to powder coated aluminum louvers at the transformers areas, the Administration Building will have powder coated aluminum curtain walls and windows to allow natural light to filter into the building.

Accessibility and Maintenance Architectural features will reinforce the functional and maintenance requirements of the facility and will not impede normal operations.

Overhead doors will be positioned and aligned to provide unimpaired movement through the full width of the door to access aisles. Overhead doors and access aisles will be provided to permit unobstructed removal and replacement of every major piece of equipment and their respective subassemblies.

A service elevator rated at 1-ton lifting capacity will provide vertical access between the ground, mezzanine and first floors of the Administration Building.

The roof of the operational plant will be accessible by three individual stair towers.

Four cranes will be provided at the ground floor of the operational plant to allow handling spare parts and maintenance of the chillers and pumps.

One crane will be provided at the roof floor of the operational plant to allow handling spare parts and maintenance of the cooling basin pumps.

Access opening (6000 x 3000 cm) will be provided in the center of the operational plant to handle equipment from the ground floor to the first and roof floors.

Access hatches will be provided to handle the generators and pumps to the basement.

Refer to Section 9 for more details on maintenance and accessibility.

Containment Requirements Electrical areas containing oil-filled transformers will be designed with passive containment provisions as required by the National Electrical Code and Stormwater Pollution Prevention Plan to prevent the accidental release of oil and to facilitate clean up and removal of spilled oil.


Building Interior The interior of the plant expansion is comprised of the basement, main operating floor, and mezzanine. The basement houses piping, pumps and water tanks related to the plant operations and a generator room containing two generators. Chillers and pumps are located on the main operating floor (ground). The first floor provides RO system as well as space for HVAC and electrical equipment.

Occupancy The plant will be occupied 24 hours per day.

The floor, walls, and ceiling of the operational and storage areas are all concrete. The floors have a transparent sealer. The walls and ceilings are painted for better light.

The lab and control room will have resilient tile. The lab has epoxy resin worktops with integral sinks.

Life safety features include an automatic sprinkler system and a fire alarm system.

Structural Design Statement

General This section of the Design Intent Report includes the narrative description of the structural systems for the Integrated District Cooling Plant (IDCP) at The Pearl, Qatar. Discussions between the Owner, Qatar Cool, PMC, the Contractor, C.A.T. International (CAT), and the Design-Build Engineer, Stanley Consultants are detailed in Exhibit A Project Correspondence.

This section includes the design criteria, subsurface conditions, foundations, building basement walls, concrete slabs on grade, operating floor over basement, and interior walls within the IDCP.

Two expansion joints will be provided for the operational plant building and one expansion joint will be provided between the operational plant building and the support space building.

Compliance Statement The Structural design will comply with all portions of the Tender Documents prepared for Qatar Cool and issued by DAR during the tender phase. These documents include the general requirements, tender specifications, room data sheets, tender drawings, and the appropriate addendums and tender circulars issued for clarification, except as noted below:


Design Criteria Codes and Standards The following codes and standards will be used in conjunction with the structural design:

BS6399: Code for Loading for Buildings

BS8110: Structural use of Concrete

Q06024-IDCP-RPT-ST-001-REV 3 4-2 Stanley Consultants

Uniform Building Code (UBC) for Seismic Loads

Design Loads The Uniform Building Code (UBC) 1997 Edition, with the following criteria:

Codes: BS 6399: Part 1 for dead and imposed loads CP3 Chapter V, Part 2, for wind loads, UBC for seismic loads.

Dead Loads:

- Concrete Unit Wt. = 24.00 KN/m3

- Floor Covering (Typical Floors) = 2.00 KN/m2

- Partition Loads (Typical Floors) = 2.50 KN/m2 for block work and 1.00 KN/m2 for Gypsum Partition.

- Floor Covering (Roof) = 2.50 KN/m2

Live Loads: The live loads will be based upon the following:

- Equipment Weight: Location and magnitude of loads will be coordinated with the mechanical design.

- Pipe Support Loads: Location and magnitude of loads will be coordinated with the mechanical design.

- Cooling Tower Weight: Location and magnitude of loads will be coordinated with the mechanical design. These loads will include the basin water weight on roof slab.

- Water Tanks: Location and magnitude of loads will be coordinated with the mechanical design.

Wind Loads: The wind load will be based upon a basic wind speed of 45 mps.

Seismic Loads = Zone 2A Seismic Risk

Load Combinations:

- 1.40 x D.L. + 1.60 x Live loads

- 1.40 x D.L. + 1.60 x Lateral Loads

- 1.20 x D.L. + 1.20 x L.L + 1.20 x Lateral Loads

Foundations:

- Foundations will be shallow foundations of raft type.

- The IDCP will have two levels for the raft foundation. The first will be under the basement floor on rock and the second will be divided into two parts on another raft found
